Floor deck bottom membrane and combined reinforced truss floor deck

Abstract

The invention discloses a bottom membrane of a floor deck, which comprises a thermal insulation board, a leak-proof board and a clamping piece. The thermal insulation plate is located on the upper side of the leak-proof plate and is clamped with the leak-proof plate. The clamping piece is fixedly connected with the thermal insulation board. The insulation board includes an insulation layer, an adhesive layer and a support layer. The support layer is bonded to the insulation layer through the adhesive layer. The support layer includes fixing bolts, the first splicing plate, the second splicing plate and a snap group. The leaky plate also discloses a combined reinforced truss floor deck, which includes the above-mentioned bottom membrane of the floor deck, and also includes a steel bar truss, an upper chord bar and a lower chord bar, the steel bar truss is located between the upper chord bar and the lower chord bar, and the upper chord bar The reinforcement is welded with the steel truss, and the lower chord reinforcement and the connecting plate cooperate with each other. On the basis of the existing technology, the structure of the bottom membrane of the floor deck is improved, and the insulation board is added, and the insulation board is attached to the poured building with fixing bolts , to improve the thermal insulation performance of buildings and avoid energy waste.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a bottom membrane of a floor deck and a combined steel bar truss floor deck. Background technique [0002] With the increasing depletion of energy, how to save energy reasonably after the construction of the building has become an urgent need. The existing floor slab will be disassembled after the pouring is completed, and the building using this pouring method is often inside The insulation effect is poor. During use, more energy will be consumed to maintain the temperature inside the building, resulting in a waste of energy in the building. Contents of the invention [0003] In order to solve the problem in the prior art that the existing floor deck needs to be disassembled after pouring concrete, and the building completed in this way has a problem of poor thermal insulation effect, which will lead to a waste of energy for the building, the prese...
